OMG! Gwen Stefani and Gavin Rossdale's family is sooooo cute!

Gwen and Gavin went for a stroll with her son Zuma, infant Apollo on Sunday in Studio City. Zuma looked like he was having a kooky time, hamming it up while walking with his rockstar mama.

We loved seeing Gavin take on daddy duty as he held his 8-month-old son close to him. It's too precious for words!

For the family outing, Gwen wore jeans, a black shirt and some eye-catching orange kicks. The Bush frontman donned an equally casual look of a white T-shirt, jeans and Nikes. The rockin' dude opted to keep out of the sun with a fisherman's hat. We couldn't help but notice that baby Apollo's onesie had trompe l'oeil checker suspenders on it -- just like mommy back in the day. Adorbs!

Even off duty, these proud parents know how to look good!
